Description of problem:
not errors, but three suggestions for cleanup of the iptables
1) line 54: chains=`cat /proc/net/ip_tables_names ...`
this variable should really be "tables", not "chains",
although this will still work since the variable is still
used consistently throughout the script. (this occurs
more than once in the script.)
2) both lines 57 and 68, which ostensibly clear entries from
the current tables, are immediately followed by a
redundant "iptables -F". again, not an error, but
confusing if you're trying to figure out what those
extra flushes are for. apparently, nothing. (this
also occurs more than once in the script.)
3) references to all possible combinations of tables and
chains do not mention the newer combinations of the
mangle table with the INPUT, FORWARD and POSTROUTING
chains, again in more than one place.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. see /etc/init.d/iptables
3) is duplicate of bug #75723.
fixed in iptables-1.2.7a-1.
